(A). Goods of handicraft
(B). Natural products
(C). Old archaeological structures
(D). Agricultural produce
Choose the correct answer from the options given below:

The 'One gene-one enzyme' hypothesis was challenged by several researchers for its validity. The reasons are-
(A). Many enzymes are composed of more than one polypeptide encoded by different genes.
(B). Product of many genes are not enzymes
(C). Genes contain introns, which do not codes for any amino acids
(D). Several related polypeptides can be obtained from a single gene through alternate splicing
Choose the correct answer from the options given below:

Merits of the Pedigree method of selection in crops include-
(A). It offers enough opportunity for natural selection to influence the population
(B). It takes less time than the Bulk method to develop a new variety
(C). Breeders get maximum opportunity to use their skills and judgment for the selection of desirable plants
(D). Transgressive segregants for yield and other quantitative traits may be recovered
Choose the correct answer from the options given below:

The objections to the 'Dominance Hypothesis' of heterosis and inbreeding depression are-
(A). Mostly, it is not possible to isolate inbreds as vigorous as hybrids
(B). Asymmetrical distribution of quantitative traits in the F2 population
(C). Magnitude of heterosis in inbred lines has increased over time, which was not expected as per the hypothesis
(D). Faster inbreeding depression in tetraploids
Choose the correct answer from the options given below:

In a mapping study, it was found that two genes- A and B are showing independent assortment. The probable reasons for this independent assortment are-
(A). A and B are not linked
(B). A and B are loosely linked
(C). A and B are located in two different chromosome
(D). A and B are located on the same chromosome but placed far away (\(>\) 50cM) from each other.
Choose the correct answer from the options given below:

Which of the following describes a 'gene' correctly?
(A). Genes are located on chromosome
(B). Gene is a discrete particle
(C). Recombination can happen within a gene
(D). One gene can encode more than one polypeptide
Choose the correct answer from the options given below:

When two lines possessing two different alleles of resistance (say, DM1 and DM2) for a particular disease are crossed, the two alleles interact to induce disease resistance response in the hybrid without pathogen attack and produce necrotic lesions. Such a phenomenon is referred to as-

In a Mendelian dihybrid cross, out of 400 \(F_2\) generation plants, how many will be homozygous for at least one gene?

If the values of phenotypic and environmental variances are 6.8 and 1.2, respectively, the heritability (broad sense) of the trait would be-

When two species can not be crossed directly due to incompatibility, a third species is used to make the target gene transfer possible, which is called as-

The transgenic tomato variety 'FlavrSavr' had a greatly improved shelf-life and general quality. Which one of the following technologies was used to achieve this feat?

For which one of the following activities, the multiple copies of a specific gene/DNA sequence obtained through PCR can NOT be used for-

Which one of the following activities is NOT practiced in the Bulk method of breeding?

'Genetic imprinting', a process of gene silencing, is postulated to be caused by-

On average, how many fragments would a restriction enzyme, which recognizes a specific 5-base sequence in DNA, be expected to cleave a double-stranded bacteriophage with a genome size of 6066 bp into?
